FIELD OF INVENTION

This invention relates to a Wireless Mobile Entertainment System. This system utilizes a Wireless Audio Device (i.e. tablet, phone, mobile computing device, or other audio or video player) to provide audio to listeners wirelessly through one or more headphones and/or speakers (or combination thereof) designed to work with the Wireless Mobile Entertainment System.

BACKGROUND

Several mobile entertainment systems are currently available. Included in this variety are versions that are permanently mounted in a vehicle, portable self-contained DVD or Blu-ray systems, individual tablets, phones, mobile computing devices, or other audio or video players with wired or wireless headphones.

One such mobile entertainment system version is permanently or semi-permanently mounted in a vehicle, either as a factory installed or aftermarket DVD or Blu-ray system with an integrated screen. These systems generally utilize an infrared (IR) signal to broadcast the audio channels to wireless headphones that users can wear. The infrared (IR) signal provides a robust method to broadcast because the signal is immune to radio frequency or electromagnetic interference that may be encountered on the road and a single transmitter can provide audio to many headphones so multiple users can share a single screen and listen to the same audio.

The disadvantages of the permanently or semi-permanently mounted in-vehicle entertainment systems are that they can be difficult to share between vehicles, requiring uninstallation and reinstallation to switch vehicles. Additionally, the use of DVD and Blu-ray discs requires users to maintain and transport a collection of DVD/Blu-ray discs in order to change what's being watched. Furthermore, these discs can be easily lost and are subject to physical damage—easily being scratched or melted in a hot car.

Another mobile entertainment system version is the Portable DVD/Blu-ray systems using wired headphones. These systems are generally hand held devices that are easily portable between different vehicles, locations, or users.

This version makes it difficult for multiple users to simultaneously share because the systems use wired headphones and rarely have enough headphone connections or output power to drive more than one or two pairs of headphones. Additionally, similar to the permanently or semi-permanently mounted in vehicle entertainment systems the users must maintain a library of DVD or Blu-ray discs, which can be easily lost or damaged.

Utilizing an individual tablet, phone, mobile computing device, or other audio or video player provides a compact entertainment system that eliminates collecting and transporting DVD or Blu-ray disc media or the risk of losing or damaging this media. Many of these devices also have the benefit of being able to play games and often are available with an Internet connection, which provides the ability to stream music or videos, or play interactive games.

As with the Portable DVD/Blu-ray systems these devices are difficult for multiple users to simultaneously share because the systems generally use wired headphones and rarely have enough headphone connections or output power to drive more than one pair of wired headphones. Devices with Bluetooth audio support can utilize wireless Bluetooth headphones for convenience, but since most can only connect to a single Bluetooth audio device it still does not allow multiple users to share. Additionally, Bluetooth headphones often have limited battery life making them not well suited for long periods of watching.

Using one tablet, phone, mobile computing device, or other audio or video player for each person in the vehicle solves many of the challenges of the previous noted systems, however these devices are often much more expensive than the other devices and use of multiple devices can be a very costly solution, even more so if each tablet has an Internet connection with added fees.

Thus, the need exists for solutions to the above problems.

SUMMARY OF THE INVENTION

The system disclosed herein is a device that provides an interface between a source audio signal from a Wireless Audio Device, such as a tablet, phone, mobile computing device, or other audio or video player, and one or more wireless headphones and/or speakers (or combination), so that the audio played from the Wireless Audio Device can be enjoyed wirelessly by multiple users. This interface provides the ease of use and variation of media of a tablet system, with the ability to be shared between multiple users and robustness of the permanently or semi-permanently mounted in vehicle entertainment systems.

Description of Device Operation

The Wireless Mobile Entertainment System 20 uses a Wireless Interface Subsystem 120 to establish a Wireless Connection 30 to an audio signal source from a Wireless Audio Device 10 via digital or analog, one or two way short range radio communication, such as Bluetooth, Near Field Communication, radio broadcast or similar interface. The audio signal is transmitted to the Wireless Interface Subsystem 120, where it can be directly passed to the Infrared (IR) Transmitter Subsystem 160, or decoded from the appropriate digital or analog signal and re-encoded into the appropriate digital or analog signal and output via digital or analog, one or two way signal to the Infrared (IR) Transmitter Subsystem 160.

The Infrared (IR) Transmitter Subsystem 160 receives the audio signal from the Wireless Interface Subsystem 120. The audio signal can be used directly to drive an output voltage/current to one or more Output Infrared (IR) Light Emitting Diodes (LEDs) 170 or decoded from the appropriate digital or analog signal and re-encoded into the appropriate digital or analog signal to drive an output voltage/current to one or more Output Infrared (IR) Light Emitting Diodes (LEDs) 170 to broadcast the audio as a one or two way, digital or analog Infrared (IR) Output Signal 50. The Output Infrared (IR) Light Emitting Diodes (LEDs) 170 may be wired in series, parallel, or a combination and arranged in a pattern so as to maximize the quality, clarity, and coverage of the broadcast of the Infrared (IR) Output Signal 50 for a specific coverage area or application.

One or more sets of Infrared (IR) Wireless Headphone(s) 60, 70, 80 receive the one or two way, digital or analog communication from the Infrared (IR) Output Signal 50, decode the audio, and output the audio to the listener's ears. The Infrared (IR) Wireless Headphone(s) 60, 70, 80 can be provided with the Wireless Mobile Entertainment System 20, purchased separately, or provide by a third party supplier.

A Charging/Power Subsystem 130 is included with one or more ports such as USB or automotive power socket ports to allow the Wireless Audio Device 10, or other device(s) to be continuously powered and/or charged, via a Charging/Power Connection 40, during use to prolong playing time.

The device can be powered via an Automotive Power Adapter 90 from a vehicles electrical system, via an AC Power Adapter 100 from a buildings power system, or via one Battery 110 or more, either internal or external to the device.
